Grails GSP - cannot call body with parameters

由 好久不见. 提交于 2019-12-10 11:53:17
问题 I have defined a taglib like this: class FooTagLib { static namespace = "foo" def bar = { attrs, body -> out << render(template: "/taglib/foo/bar", model: [body: body]) } } The body closure takes two parameters, baz and qux, why can't I do this in my /taglib/foo/_bar.gsp: ${body(baz: 'Hello', qux: 'world!')} ? This is how I use this tag in my gsp views: <foo:bar> ${baz} ${qux} </foo:bar It prints the content of the body, but the parameters are all null : null null Is this a bug or is there
